Ch 46: Developmental Mechanisms for the MCAT: Help and Review

About This Chapter

The developmental mechanisms chapter of this MCAT Help and Review course is the simplest way to master developmental mechanisms. This chapter uses simple and fun videos that are about five minutes long, plus lesson quizzes and a chapter exam to ensure students learn the essentials of developmental mechanisms.

Who's it for?

Anyone who needs help learning or mastering MCAT material will benefit from taking this course. You will be able to grasp the subject matter faster, retain critical knowledge longer and earn higher scores. You're in the right place if you:

  • Have fallen behind in understanding the molecules that control cell development
  • Need an efficient way to learn about developmental mechanisms
  • Learn best with engaging auditory and visual tools
  • Struggle with learning disabilities or learning differences, including autism and ADHD
  • Experience difficulty understanding your teachers
  • Missed class time and need to catch up
  • Can't access extra MCAT review resources at school

How it works:

  • Start at the beginning, or identify the topics that you need help with.

Students will review:

In this chapter, you'll learn the answer to questions including:

  • What is Spemann's organizer?
  • How can concentration gradients be used to create various combinations of signaling molecules in an embryo?
  • What does it take for a cell to differentiate?
  • What fate mapping techniques can be used to track cell development?

Spemann's Organizer: Controller of Cell Fate

1. Spemann's Organizer: Controller of Cell Fate

Spemann's organizer is a small group of cells in the human body that controls cell fate and determines how an embryo develops. Learn about embryo experiments conducted by Wilhelm Roux, Hans Driesch, and Hans Spemann and the three major body axes.

Concentration Gradients, Signaling Molecules & Inhibitors in Development

2. Concentration Gradients, Signaling Molecules & Inhibitors in Development

A developing embryo has a complex regulatory system. Learn about Spemann's organizer, which is the source of a number of different proteins, learn about other parts of the embryo development process, including concentration gradients, and explore the complexity of the differentiation process.

How Signaling Molecules Control Differentiation

3. How Signaling Molecules Control Differentiation

During the early stages of the maturity of an embryo, each cell undergoes a process called differentiation, which determines the function and specific type of the cell. Learn about the process of differentiation, the different types and functions of signaling molecules, and how these signaling molecules control the differentiation of cells.

How Fate Mapping Is Used to Track Cell Development

4. How Fate Mapping Is Used to Track Cell Development

Fate mapping is the process of tracking cells using dyes to monitor how they grow and develop as an organism matures. Learn about fate mapping processes developed by an embryologist in 1929 for mammals and non-mammal, and discover how advances in science and technology and even dyes have improved fate mapping.
